News items - Add a New Comment - HOW TO?

Does anybody have an idea how to post a comment on a news article? Mine always has a text box with a "Please Wait . . . " in it.

To see what I mean, go to PCA home page, click any news article and underneath the article there's a comments section.

I see a few comments have been added to various articles but I am unable to do so.

There is a "Login" button (link) which opens a Login or Register box with various options - so do we have to log in to post a comment now? It always used to be there and anonymous (if that was what you wanted) but now we have to use our Facebook or Google id - is this right?

When I tried, (already logged in to pca forum) and clicked on 'Post As...' I got a pop up box 'Who are you?' with my details already filled in - my email address and name it showed my real name and not my forum user name.

Perhaps these are editable but I didn't post a comment just in case (I chickened out)

I tried several articles but couldn't find any with any comments already on?
